Currently automobile is moving towards light-weight trend, compact structure, large power, good accelerating ability, comfortableness, safety, durability and high unfailing performance and so forth. Furthermore, due to the progress of electronic control technology, automobile also moves towards practical performance such as low consumption, good form performance and convenience. Hence, as an important part of car support, antifriction bearing has to adapt to this development tendency. Based on these features, Xinghuan Bearing devotes itself to the research and development of automobile bearing and engineering machinery bearing.
